ANALYSES OF HORIZONTAL LOADING TESTS ON FRANKI PILES

The behaviour of single piles, subject to horizontal loading at the top, can be predicted by a method which uses A hyperbolic relationship between soil pressure and pile deflection. The method is applied to full-scale tests on two franki piles tested up to a maximum horizontal load of 25 t. Pile stiffness as measured in the laboratory was found to decrease rapidly with increasing bending moment. Two calculations were carried out to predict the pile performance, one with the real ei obtained from laboratory tests and another with a constant ei over the whole length. The calculations show that exact values of pile stress must be considered when horizontal loads become significant. (TRRL)
